Abstract
An ablation apparatus for creating a lesion in target tissue, the ablation apparatus including a handle, an elongate shaft extending from the handle to a distal tip, where the shaft includes a first portion, an ablation portion distal to the first portion and having an outer sheath, and at least one ablation energy element disposed within the outer sheath, where a space is formed between the at least one ablation energy element and the outer sheath. The ablation apparatus further includes a thermally conductive liner disposed within the space.
Claims25
An ablation apparatus for creating a lesion in target tissue, the ablation apparatus comprising:
- a handle;
- an elongate shaft extending from the handle to a distal tip, the shaft comprising:
- a first portion;
- an ablation portion distal to the first portion;
- and
- at least one ablation energy element disposed along the ablation portion, wherein a space is formed between each of the at least one ablation energy elements;
- and
- a thermally conductive liner disposed within the space.
An ablation system for creating a lesion in target tissue, the ablation system comprising:
- a catheter comprising a handle, a distal tip, and an elongate shaft extending from the handle to the distal tip, the shaft comprising:
- a first portion;
- an ablation portion distal to the first portion;
- and
- at least one ablation energy element disposed along the ablation portion, wherein a space is formed between each of the at least one ablation energy elements;
- and
- a first thermally conductive liner disposed within said space;
- and
- an energy generator coupled to the catheter to deliver and control the ablation energy from the at least one ablation energy element to the target tissue.
An ablation catheter for creating a lesion in target tissue comprising:
- an elongate shaft extending from the handle to a distal tip, the shaft comprising an ablation portion distal to the first portion;
- at least one ablation energy element disposed along the ablation portion and defining a space between each of the at least one ablation energy elements;
- and
- a thermally conductive liner disposed within the space.
